SINOTRUK HOWO SITRAK TRUCK Power Take-Off WG9700290180

It is mainly matched with HW series transmissions (such as HW19710, HW19712, HW25712, etc.).

FUNCTION

1. Power Transfer: This is the most important function of this component. Installed in the rear window of the Sinotruk HW series gearbox, it uses mechanical gears to extract the rotational power generated by the engine from the gearbox and convert it into mechanical energy usable by external equipment.

2. Driving Hydraulic Systems: This model uses an ISO 4-hole standard flange interface, primarily for directly connecting and driving hydraulic pumps (such as gear pumps or piston pumps).

Dump Trucks: Drives the hydraulic oil pump to provide pressure to the hydraulic cylinders to lift the truck bed.

Concrete Mixer Trucks: Drives the hydraulic motor or pump to keep the tank rotating.

Truck-Mounted Cranes: Provides power to the crane's hydraulic extension and lifting mechanisms.

3. Remote Pneumatic Control: This power take-off unit integrates a pneumatic control valve (cylinder), allowing the driver to engage and disengage power from inside the cab via a pneumatic switch. This ensures that power output can be cut off during driving, reducing wear and fuel consumption.

4. Mechanical Protection and Transmission Matching
Speed ​​Matching: The internal gear ratios are designed to ensure that the output speed matches the optimal operating range of the hydraulic pump.

Installation Location

The countershaft window is located at the rear of the transmission. During installation, the original vehicle's transmission rear sealing cover needs to be removed, and the extended shaft of the PTO needs to be inserted into the countershaft inner hole.

Performance Advantages

1. High-Strength Precision Gears: The internal gears are made of high-strength alloy steel and treated with carburizing and quenching processes, resulting in extremely high wear resistance and impact resistance, ensuring no tooth breakage under high-load lifting operations.

2. Perfect System Compatibility: Designed specifically for Sinotruk HW series gearboxes, the extended shaft dimensions are precise (240mm), and the mounting position is perfectly matched, requiring no additional modifications, reducing installation costs and the risk of oil leaks.

3. Responsive Pneumatic Control: Equipped with high-performance cylinders, the shift stroke is precise, and the response speed is fast. Pneumatic control ensures the safety and convenience of indoor operation for the driver.

4. Standardized ISO Flange Interface: The output end adopts an international standard ISO 4-hole flange, which can be directly connected to mainstream brand gear pumps such as Hyva, ensuring strong interchangeability and facilitating later maintenance.

5. Optimized Lubrication & Cooling: The housing design optimizes the lubrication channels, achieving excellent heat dissipation through gearbox splash lubrication, supporting long-term continuous operation without overheating.
